3nventor Amman- C. A. YOUNG FIREARM Filed June 24, 1940 Patented May 28, 1946 UNITED srras PATENT 2,401,034 FIREARM Charles A. Young, Springfield, Ohio Application June 24, 1940, Serial No. 342, 07 3 Claims. (01. 42-70) This invention relates to improvements in firearms, it more particularly relating to either double barrel or single barrel shot guns and espe-- cially to means for locking the trigger or triggers, which means is operated the pressure of the shooter.

One of the objects of the invention is to provide a locking device of this character which can be readily installed in a conventional type gun without disturbing the firing mechanism of the gun and in which the firing mechanism or parts thereof of the gun may be readily removed Without disturbing the connections which lead from the shoulder piece to the locking device.

A further object of the invention is to provide a pivoted locking device for the trigger or triggers of the gun which is operated from the shoulder piece and which may be readily applied to the support for the firing mechanism without disturbing the mechanism.

In the accompanying drawing:

Fig. 1 is a side elevation partly broken away and shown in section of a modified form of the invention, the trigger in this case being shown locked.

Fig. 2 is a side elevation partly broken away of some of the parts shown in Fig. 1 but showing the locking device for the trigger in inoperative position.

Fig. 3 is a section on the line 3-3 of Fig. 2.

In the drawing there is illustrated an embodiment of the invention wherein 51] represents the housing which encloses the firing mechanism and 5! indicates the gun stock. The impact member or hammer is indicated at 52, the finger piece of the trigger at 53 and the sear which locks the hammer at 54, the sear in the present case being integrally formed with the trigger. The trigger is pivoted as at 55 on a removable support 56 which forms the bottom of the housing and the free end of the sear engages with the sear notch in the hammer to hold it in retracted position; the hammer being pivotally mounted on the support by the pin 51.

In order to lock the trigger until the gun is pressed against the shoulder there is provided a latch 59 which is pivoted intermediate its length at 60 to the support. The lower end of the lower arm of this latch is formed with a reduced projection Bl which is adapted to engage in a notch 62 in the finger piece of the trigger for locking purposes. The upper arm of the lever extends loosely through a slotted gun upon the shoulder of the to unlocking position by 1 spring is interposed opening 63 in a pin 64 which is slidably mounted in a longitudinal bore in the support 55. A coil between the forward end of the bore and the pin to normally project the pinto the position shown in Fig. 1 which carries the reduced end 5| of the locking lever into the notch 62 of the finger piece so as to lock the trigger. In order to release the locking latch from the trigger a shoulder piece 10, preferably of'soft vulcanized rubber or other resilient material, having therein' a chamber 69, the open face of which is contiguous'to the butt of the gun stock. Extending through the gun stock is a ngitudinal bore] through which'projects a reciprocatory rod 66. The rear end of the rod 66 is pivotally connected to a ,boss 67 on a plate 68 which is "located in a chamber 69 in the resilient shoulder piece 70. A coil spring 1| interposed between the end of a thimble l2 and the boss serves to press the plate 68 against the inner wall of the chamber 69 and holds the rod in so long as no pressure is applied to the shoulder piece '15. When the resilient shoulder piece is pressed against the shoulder of the shooter the rod is projected forwardly into engagement with the ,pin 65 so-as to throw it to the position shown in Fig. 8 against the tension of its spring 65 and thus rock the locking latch 59 to the position shown in Fig. 2 to release the trigger. Thus, it will be seen that those parts of the firing mechanism such as the trigger, sear, the locking latch 59 and the pin 54 and also the hammer may be readily removed without disturbing the operating rod 65 and its connections. Further, when applying the instant control means to an existing firearm the original support may be readily modified to permit the installation of the trigger latch without disturbing the original firing mechanism.

In the construction illustrated in Figs. 1, 2 and 3 the pin 65 upon which the latch 59 is pivoted may be removed so that the latch 59 may be readily removed if it is desired to restore the gun to its original form. In this case the pin E i and spring 65 may also be removed.

The present application Serial No. 342,007 has been divided, and the remainder thereof has been presented as a continuing application Serial No. 612,181, filed August 23, 1945.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more invention into effect, and the invention is therefore claimed in any of its forms or modifications I within the legitimate and valid scope of the appended claims.

Having thus described my invention, I claim:

1. In a gun having a stock and a receiver, a fire control mechanism comprising an im'riactmember and a trigger having a finger piece, a sear for said impact member controlled by said trigger, a removable support forming the bottom of said receiver upon which said sear and trigger are mounted, a latch for said trigger pivotally mounted on said support and engageable with the trigger to lock the same against movement, a slidable pin in said support having a slot through which said latch extends, a spring acting on said pin to normally hold said latch in engagement with said trigger finger, and shoulder-operated means to operate said pin to release said latch from said trigger piece.

2. In a gun having a stock and a receiver, an

impact member, a trigger having a finger piece,

a sear for said impact member; controlled by said trigger, a removable support forming the bottom of said receiver upon which said sear and trigger are mounted, a latch for said trigger medially pivoted on said support and including an end engageable with the trigger to lock the same against movement, a slidable pin having a slot through which said latch extends, a spring acting on said pin to normally hold said latch in engagement with said trigger finger, a yieldable shoulder piece carried by said stock and yieldable under pressure against the shoulder of the shooter; a thrust rod' independent of, said pin extending from said shoulder piece to said pin and operative to longitudinally move the pin to disengage the latch from the trigger, and a spring normally holding said rod in operative relation with said shoulder piece said latch operating pin being mounted in said support for removal as a part ofthe unitary support assembly, leaving the thrust rod remaining in the stock.

3. In a gun having a stock and a receiver, an impact member, a trigger having a finger piece, a sear on said impact member controlled by said trigger, a removable support forming the bottom of said receiver upon which said sear and trigger and its finger piece are mounted, a latch for said trigger pivotally mounted on said support and engageable with the trigger finger piece, a removable slidable pin mounted on said support'and removable therewith, and having a slot through which said latch extends, a removable spring acting on said ,pin to normally hold said latch in engagement with said trigger finger piece, and shoulder-operated means independent of said pin to operate said pin to release said latch from said trigger, said pin and latch being removable from the gun as a part of the unitary support assembly.
